About NetProceeds

I’m Marcus Delgado. I’ve been selling online full-time since 2011 — over 30,000 orders across a dozen platforms, run out of a garage office in Columbus, Ohio. Vintage denim and sports cards are my lanes. I started on eBay back when the fee statement was one line, added Poshmark, Mercari, and Depop through the mid-2010s, and these days I spend Friday nights running live sales on Whatnot.

NetProceeds exists because of a $4 mistake I made roughly four thousand times. Early on, I priced everything by gut feel and found out at payout time what the platform actually kept. Multiply a few misjudged fees across thousands of orders and you’ve funded someone else’s vacation. Knowing your net before you list isn’t a nice-to-have — it’s the whole game.

What this site does

One marketplace fee calculator that compares your net profit across 13+ platforms at once, plus a dedicated calculator for each platform with reverse mode — “I want to net $X, what should I list at?” Everything computes in your browser. No signup, no email gate, and your numbers never touch a server.

How I verify the rates

Every rate on this site is pulled from the platform’s official fee schedule — not from other fee blogs, which is how stale numbers spread. Each calculator shows its verification date and links its source. I re-verify all 13 schedules quarterly, and any time a change is announced (or quietly shipped — Cash App, looking at you), the calculator gets updated and the change gets logged publicly on the fee changes page with a date and a source.

The calculation engine itself is tested against 42 known-answer cases before every release — including the platforms’ own published worked examples, like Whatnot’s official “$50 item → $44.00 take-home” example. Where a platform doesn’t publish a rate (Cash App’s exact instant-deposit percentage, Depop’s per-order buyer fee), the calculator says “estimate” out loud instead of pretending.

What this site doesn’t do

It doesn’t give financial advice, it doesn’t predict what a platform will charge you in edge cases their docs don’t cover, and it doesn’t pretend affiliation with any marketplace — see the disclaimer. Estimates are estimates. They’re just verified, dated, honest ones.

Something wrong? A fee I missed? Email me — payout screenshots welcome. The fastest corrections come from sellers who caught a fee in the wild.
